Duplicate the configuration of virtual servers on Big-IP LTM
Hello everyone,
I have approx. 50 existing virtual servers on Big-IP LTM. I need to create an exact copy of each virtual server but with different virtual-server's IP. creating 50 copies from GUI seems very difficult and tedious task. so I wanted to ask if there is a better way to duplicate the virtual servers.
One of the possible options I can think of is using CLI. capture the existing configuration of virtual-server by running 'list ltm virtual <virtual-server-name>', change the IP and push it back via CLI. I have never done before so not sure if it is safe to use CLI for such bulk configuration changes?
If anyone knows a useful KB, document, please let me know.
Thanks all,
Hi,
You can use an scf backup and load it via the cli.
save /sys config file my-scf no-passphrase
Look for it in /var/local/scf
Loading it back after the modifiations:
load sys config from-terminal merge verify or load /sys config merge file <filename> verify if it runs without errors load sys config from-terminal merge or load /sys config merge file <filename> save sys config

Thank you Kees, that's very helpful. Is this procedure safe? looks like I'm backing up the entire configuration and then loading it back with changes. I'm afraid if I mess up while editing it, it can have huge ramifications.
Hi,
With an SCF backup you get a txt file. Modify the entries you need and remove the rest.
With the verify command you make sure that you are not messing up.
Cheers,
Kees
